是的,几年前就已经在这里被询问和回答了。
我唯一的问题是答案与现实不符。应该重用FTP连接,但它不是,我的curl版本是7.44.0 32/64位,OS: linux/AIX。详细模式和tcpdump都证明了每个文件上传都会打开一个新的连接。另外,在url.c中也有这个部分。
/*
* IsPipeliningPossible() returns TRUE if the options set would allow
* pipelining/multiplexing and the connection is using a HTTP protocol.
*/

port install arm-none-eabi-binutils
我在我的mac上下载了arm工具。
export CCPREFIX=/opt/local/bin/arm-none-eabi-
make ARCH=arm CROSS_COMPILE=${CCPREFIX}
however it has alot of errors.
tcpdump.c:180: error: ‘struct tcphdr’ has no member named ‘source’
tcpdump.c:238: error: ‘ETH_P_A
在我现在正在测试的Linux系统上,它有两个虚拟L2设备链接在一起,以添加/操作我们自己的帧标头,这些帧头被封装在Eth报头和IP报头之间。
下面是"tcpdump -xx -i virtual_if_1“为捕获的传出数据包所显示的内容。
tcpdump: WARNING: xxxtype 1000 not supported by libpcap - falling back to cooked socket
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

我想在我的Ubuntu中安装以太网,但是错误消息仍然是这样发生的:
tcpdump: eth0: No such device exists
(SIOCGIFHWADDR: No such device)
